Overview
Anti-TRPV3 (extracellular)-ATTO Fluor-633 Antibody is an antibody targeting Transient receptor potential cation channel subfamily V member 3, Vanilloid receptor-like 3, VRL3 Polyclonal raised in Rabbit (ATTO-633. Maximum absorption 629 nm; maximum fluorescence 657 nm. The fluorescence is excited most efficiently in the 610 - 645 nm range. This label is analogous to the dyes Alexa 647, Alexa 633 and Cy5 and can be used for direct flow cytometry (FACS) using the He:Ne laser.). This antibody is commonly used in FC, IC, IF, IHC, LCI to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Transient receptor potential cation channel subfamily V member 3, Vanilloid receptor-like 3, VRL3 (also reported as Transient receptor potential cation channel subfamily V member 3, Vanilloid receptor-like 3, VRL3).
- Immunogen/epitope region: 1st extracellular loop.
- Homology note: Rat - 13/15 amino acid residues identical; mouse - 12/15 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Human, Rat, Mouse.
- Lot quality control (as provided): Western blot analysis (unlabeled antibody, #ACC-033), and immunohistochemistry (labeled antibody)..
- Peptide confirmation: Confirmed by amino acid analysis and mass spectrometry.
- Blocking peptide: Available for antigen preadsorption control where appropriate.
- Conjugate/format: ATTO-633. Maximum absorption 629 nm; maximum fluorescence 657 nm. The fluorescence is excited most efficiently in the 610 - 645 nm range. This label is analogous to the dyes Alexa 647, Alexa 633 and Cy5 and can be used for direct flow cytometry (FACS) using the He:Ne laser. (may affect detection channel and background).
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
TRP channels are a large family (about 28 genes) of plasma membrane, non-selective cationic channels that are either specifically or ubiquitously expressed in excitable and non-excitable cells.1 The TRP channels have six putative transmembrane domains (TM) with a pore domain between the fifth and the sixth TM, and all assemble as tetramers. Both the N- and the C-terminus of all TRPs are intracellular.3According to IUPHAR, the TRP family is composed of three main subfamilies on the basis of sequence homology; TRPC, TRPM and TRPV (to date, three additional subfamilies are also considered to belong to the TRP family: the TRPA, TRPML, and TRPP).1-4 The TRPV subfamily consists of six members, TRPV1-6.5Four members of the TRPV family have been described as a thermosensitive ion channels (TRPV1 to TRPV4). Each channel exhibits distinct thermal activation thresholds ranging from noxious cold (52°C).6,7TRPV3 is highly expressed in skin keratinocytes.
Research relevance and current trends
- Linking transporter/channel abundance to ionic homeostasis and excitability-related phenotypes.
- Studying compartment-specific localization (surface vs intracellular pools) and trafficking dynamics.
- Combining antibody readouts with functional assays for more complete interpretation.
Common research applications
- Immunohistochemistry (IHC): examine spatial distribution in tissue and relate signal to cell-type composition.
- Immunofluorescence/ICC: assess subcellular localization and co-localization with markers in cells or sections.
- Flow cytometry (direct/indirect): quantify target-positive populations and shifts in expression across subsets.
- Live cell imaging (LCI): support extracellular-epitope detection on non-permeabilized cells when appropriate.
Interpretation typically benefits from comparing matched sample sets (e.g., treated vs control, WT vs KO/KD) and using orthogonal readouts where feasible.
Notes for experimental interpretation
- Isoforms and post-translational modifications can shift apparent molecular weight or epitope accessibility across samples.
- Cross-species signal may depend on epitope conservation; consult the provided homology note when selecting models.
- Permeabilization, fixation, and antigen retrieval can change accessibility of intracellular vs extracellular epitopes.
- Conceptual control: antigen preadsorption (blocking peptide) can help assess signal dependence on the immunogen region.
- Provided control suggestions: Negative control: BLP-CC033.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
